1) Drill 7/32-inch holes thru the center of the golf balls. The golf balls are even more difficult to drill than the PVC caps, so use the same channel lock pliers to hold the golf balls. Be sure to use a cloth rag or piece of rubber on the pliers to protect the surface – you do not want sharp edges on your bolas.
2) Cut the paracord into pieces 12-inches long. Singe the edges of the paracord with a lighter to stop it from fraying.
3) Put an overhand knot into the paracord about 1/4-inch from one end. Thread two matching golf balls onto the paracord – use a short piece of wire to push it thru if needed – and then put another overhand knot about 1/4-inch from the other end of the paracord.
4) Lock the golf balls onto opposite ends of the paracord with another overhand knot on each end.
